SPECIFICATION forming part of Letters Patent No. 660,998, dated October30, 1900.

Application filed August 21, 1899.

To (1 whom it may concern.-

Be itknown that 1, ROBERT R. RAYMOND,

a citizen of the United States, residing at Boston, in the county ofSudolk, State of Massa- 5 chusetts, have invented a new and usefulImprovement in Hoisting Apparatus, of which the following is aspecification, reference being had to the drawings accompanying andforming a part thereof.

The present invention relates to hoisting apparatus, and is especiallydesigned to .be used in connection with heavy ordnance for the purposeof elevating individual charges from a lower plane, as an ammunitionstorage- 5 room, to a higher plane, as the point of support of a gun.

The object of the invention is to provide a simple means whereby theheavy cartridges or shells may be easily handled and placed upon anendless traveling device and automatically discharged at the point ofdelivery in an easy manner, so that there shall be no danger ofexplosion of the charges. At the same time the construction embodyingthe invention is such that the discharging devices are of the simplestcharacter aud'operate positively.

In the drawings I have illustrated econ struction emoodying myinvention, which, 0 while it"'shows one form of my invention which Ideem now'to he a preferred form, I do not wish to be limited thereto, asthe construction may be susceptible of variation without departing fromthe spirit of the in- In the drawings, Figure 1 is a view partly in sideelevationand partly in vertical crosssection. Fig. 2 is a detail view inelevation of one of the carriers. Fig. 3 is an elevation 40 view oftheloading devices looking in the direction of the arrow of Fig. 1. Fig.4: is a plan view of the loading devices.

Like letters of reference refer to like parts throughout the severalviews of thedrawings.

Referring to the drawings in detail, 1 designates-the lower frame of theconstruction, which may beef any suitable form and supports-a shaft 2,on which are keyed sprocketwheels 3.

5o 4 designates the upper shaft, upon which are secured the uppersprocket-wheels 5.

Serial No. 727,875- (No model-l -maiutain while they pass a portion ofthe curved surface of the upper sprocket-wheels and, in fact, until theycome in contact with the tilting or tripping device to efiect thedischarge. of the load. Each of these carriers consists of a bottomplate 10 and a tailpiece 11, being secured to the chains by thesidepieces 12; but other forms of carrier may be used that will perform thefunctions herein described.

The means whereby each of the carriers automatically picks up its loadand discharges the same consists of the following: Near the upper end ofthe travel of the chains and between the upward and downward ascendingand descending chains is a guide-piece 13, which receives the carriersimmediatelyafter they have discharged their loads. Atthe time ofdischarging the load the carrier is in inverted position, and this guide13 operates to 8d maintain it in that position and at the same time todeflect it from the central vertical line of the apparatus until attheend of said guide 13, which iscurved outwardly, the carrier, by reasonof the fact that its center of gravity is gradually deflected upon theopposite side of'the central line of the descending chains, is

thrown upon the guideway or track 14, which maintains it in invertedposition throughout the remainder of the downward travel. The reason forthis is that the load which the carrieris to take up is taken on at thelowermost point of the chain and the carrier is to scoop up or pushalongits load until it is entirely supported upon the carrier.

The means whereby the load is thrown in the path of the carrier andautomatically taken upgthereby consists of the following: At thelowermost point of the travel of the two chains is a loading-table 15,provided with two pivoted segments 16, haviu g a curved face17,-feoinciding with the circumference of ;.:su:rface 17 of the pivotedsegments.

This loading-table is also'provided with two upstanding arms .18, whichare provided with acurved portionlll, which constitutes acontinuationoft-he curved The segments before referred to are secured to a i -shaft20 andar'e moved by any desirable "-means, as 'a ha'ndle21. =Any uitablelocking in the drawings I have shown bolt 22.

device may be provided for this handle, and

asimple pushllh'e downward guide 14 terminates .in a curved portion 23,which meetsa curved from chain to chain.

It is evident that-the loading devices may be variously modified so longas there are present a platform for the load at the lowermost path oftravel of the carriers, a table or other means for feeding the load tothe platform either separate from or integral with the platform, and aninclined or curved surface or guide, which may be either part of theplatform or separate therefrom, as shown inv the drawings, the purposeof whichis to keep the load in engagement with the carrier until it issupported thereby or t'heir'equitralents. '3

As the carriers ascendeupon the endless chains and approach the upperspr9cket= loading-platform 24, extending clear across fwheels theirvertical positionjs maintained by reason of the method ofsuspension'until the load has passed the central shaft band ings the load is-take.the', tailpiece" 1l of the carrier comes in contact with tiajtf 'haft4. The further movement of en chains then eflfects a tilting' of the ca'r,-= as-illu strated inFig. 1,,so thatthe load s discharged. upon thereceiv ing-table 25. ffitter this,a;as before described," the carrieriscar'ried downward in an inverted positioniby meansphth'e guides 13 and14.

In the mechanism-'1 lnsti'ated in the draw- I t uplas follows: Asuitable shell or other load is placed'upon the table 15, the. segments16 are lowered by means of the'cranlf21, and the shot or. other "loadrolls forward upon said segments,and as the segment's are-brought up toa normal positi'on the float-dis, throw'nupon the loadingplattormdirectly in the path of travel of the carriers and the segments areclosed or locked by means of the 'pu'sh-bolt 22. The next carrier whichcomesalong will'engage or scoop,

up theshell or other object constituting the .load and carry-it toflthejpoint of delivery, as

before explained It for anyreason the segments 16 shouldjnot be lockedin their closed or normal position, the carrier-would simply pushdtheload oifi; of the wayand would pass on without'takiiigj'it'up.

. I have 'aho, e illustrated auddescribod-the preferred foirms of myconstruction and'of the severalpartsthereof. Itis evident, however,"thatvarious changes and modificatiens of the same may-be made withoutdeparting from the spirit of my invention,and I do notintend, theretore,to limit myself to the specif c coneeoeos struction shown.- I intendalso when using the word chains in the specification and claims toinclude therebythe use of a single chain when desirable.

The ad vantages of my construction will be apparent. The loads, whichmay be shot or anything else, are engaged by the carrier at! the lowestpoi nt of its travel and carried clear around to the opposite side ofthe endless chains and automatically discharged -there by means at thesame timesimple and positive. Also the labor required for loading thedevice is of the very smallest degree and. the pick-up is automatic.

4. In an apparatus of the character described, endless chains,one ormore carriers freelysuspended between said chains,.a platform at thelowermost path of travel .of the partly-inverted carriers, meansforpresenting the carriers to the platform inapartlyinverted position,and movable guides for automatically keeping the load in engagement withthe carrier until supported thereby, substantially as specified.
